Abstract

A casing recoil steam turbine is a device which is characterized in that a power rotor integrates a nozzle spray pipe, a power disc, a pressure-gathering casing and a rotating shaft into a whole, high-pressure steam enters a pressure-gathering chamber from an input pipe through the axis of the rotating shaft and the vicinity of the axis of the rotating shaft and is sprayed out from a nozzle to generate power, and a steam condensing chamber is a supporting casing. The high-pressure steam ejected by the multistage stationary blade cascade nozzles of the existing steam turbine is changed to push the multistage movable blade cascade to do work, so that the volume of the mechanism with the same power is reduced, the weight is reduced, and the heat loss is reduced.

Description

Shell counter-impacting turbine

The utility model relates to a kind of engine device, and relating in particular to a kind of is the housing recoil steam turbine of working medium with the high pressure steam.

Existing is that the steam turbine of working medium is made up of static cascade and two kinds of principal organ of moving blades and poly-press shell with the high pressure steam, and high pressure steam sprays at a high speed from generator (or boiler) input static cascade and promotes moving blades and do work.This steam turbine single-stage thermal conversion rate is low, and multistage thermal conversion rate is higher.The multistage steam turbine requires high on make producing, complex process, from actual production, draw " during worker that 200,000 kilowatts steam turbine is every kilowatt, only be 100,000 kilowatts of steam turbine about 63 percent ".Therefore existing steam turbine has good economic benefit at high-power producer mask.It is higher that existing steam turbine static cascade ejection high pressure steam promotes the moving blades acting proportion of goods damageds, and its thermal conversion rate is about 30 percent.

The purpose of this utility model is on the basis that has kept the steam turbine advantage, make a kind of mode that promotes the moving blades acting by static cascade nozzle ejection high pressure steam that changed, by collection jet pipe nozzle, the kinetic energy dish, poly-pressure shell rotatingshaft is in one, the housing recoil steam turbine that the unit output power is improved.

The utility model is achieved in that the high pressure steam that steam generator (or boiler) produces enters rotatingshaft passage and poly-pressure shell by supplying tube, enter barometric pressure from jet pipe and nozzle along the ejection of kinetic energy dish circumference point of contact tangent direction, the stressed opposite direction towards the steam ejection of kinetic energy dish rotates.High pressure steam is ceaselessly supplied with, and the kinetic energy dish gyrates, and realizes power output.Whole concrete structure removes steam generator, it is outward the power plate (1) of the connection high pressure steam jet pipe of cooling chamber shell (6) support in addition by support that condensing plant and condensed water return voltage indicating device, the poly-chamber (4) of pressing of steam is arranged in the power plate, gather and press the outdoor poly-chamber shell (3) of pressing that has; With the poly-high pressure steam input channel (13) of pressing the rotatingshaft steam inlet that the high pressure steam input is arranged that the chamber communicates and passage (10) and connecting steam generator, passage (13) is outer to be supplying tube (12); The poly-chamber of pressing also communicates with each high pressure steam jet pipe and nozzle (2); Jet pipe and nozzle (2) steam of ejection at a high speed enter condensation chamber (5), and the water of vapor condensation returns boiler from reflow pipe (14) by back pressure mechanism.In rotatingshaft (9) outside bearing (8), seal ring (7), capsul (11), condensation chamber shell (6) are arranged in order respectively; Rotatingshaft (9) axle center, intermediate portion and near or the axle center of one end and near rotatingshaft input steam inlet and passage (10) are arranged, high pressure steam is to realize the purpose of doing work then by near the poly-pressure of input chamber axle center or the axle center.

The utility model compared with prior art its good effect is: (1) because the rotatingshaft of this device, poly-to press chamber, power plate, spray vapour device be a dynamic entirety, (and held supporting) by the condensation chamber columella compares with static cascade, moving blades and poly-existing steam turbine of pressing the chamber to set up separately, volume is little, in light weight, power consumption is little, consumptive material is few; (2) to make thermal power transfer be that the loss of mechanical energy is minimized to the structure of this device.It is identical that its mechanism's single action can be coiled with many kinetic energy dish hot merit conversion ratio, therefore the large, medium and small various steam turbine of this novel suitable manufacturing.

Describe the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a positive view of the present utility model.

Fig. 2 can coil side sectional view for single action of the present utility model.

Fig. 3 is many kinetic energy dish side sectional view of the present utility model.

Shown in Fig. 2-3.The difference of Fig. 2 and Fig. 3 is: Fig. 2 can coil device for single action, and its high pressure steam gathers pressure chamber (4) and realizes the high pressure steam acting from an end axle center and near (10) input thereof of rotatingshaft, and the other end of axle is a power output load end; Fig. 3 is many kinetic energy dish installation drawing (steam turbine divides single action can coil and many kinetic energy dish structure), its high pressure steam is to enter and poly-ly press chamber (4) and realize the high pressure steam acting from entering rotatingshaft steam inlet and passage (10) by supplying tube (12) by (13) between per two kinetic energy dishes, the one end sealing of axle, the other end is a power output shaft.The hot merit that single action can be coiled with many kinetic energy dish structure can the rate of changing be the same.

Theoretically, the steam turbine of prior art is that static cascade nozzle ejection high pressure steam promotes the moving blades acting, and steam repeatedly increasing temperature and pressure classification promotes multistage moving blades acting by the ejection of static cascade nozzle.The energy of static cascade nozzle ejection high pressure steam can only farthest be converted into output kinetic energy by multistage moving blades, but can only be less than the energy of its static cascade nozzle ejection high pressure steam, yet its high pressure steam of housing recoil vapor wheel mechanism (promptly this is novel) that integrates rotatingshaft, poly-pressure shell, kinetic energy dish, jet pipe nozzle is to spray from circumference point of contact, power rim tangent direction, kinetic energy and the kinetic energy of ejection high pressure steam examine and seize the kinetic energy direction opposite, equal and opposite in direction (according to Newton's law active force and reaction force opposite sign but equal magnitude).Therefore this novel conversion ratio of hot merit in theory will be than existing steam turbine height.

Structure of the present utility model has possessed makes big, many kinetic energy dish of mid power and the steam turbine that low power single action can be coiled.If with the medium and small power generating equipment of the supporting exploitation of the generator of corresponding power, set up medium and small power station (station), make the village in wide mountain area, Plain and general industrial enterprise with its power station of investing to build oneself that can bear, the life that can be convenient for people to effectively and improve its labour productivity; Be driven machinery support with other and can be widely used in industry, traffic, agricultural, national defence and people's life.It will be that a kind of be easy to promote the use main is the efficient height of the energy with cheap fossil fuel as further exploitation, the steam turbine of new generation that cost is low.
